I'm very serious about investing and my house is currently under contract to be sold, so I want to invest the profit wisely. 

Our plan has been to work on this house, save as much money from our 9-5's as possible and learn as much as we can through books, forums and mentors before selling and using the profits to get into multi-family units.

Keep in mind,  rentals don't show profit at first.

The way to get your profit is to get a mortgage from the seller that will go on closing statement.   

I'm having a hard time understanding if I could profit off Renting the house and Airbnb the cabin with a little work.

Probably $0 down payment.He'll offer you below market rent so that he can then rent it to someone else and profit off of the difference.

I run a non profit that helps people find work at no charge, maybe I can help.

If I can make it work, it would save me a substantial amount of taxes.I would then plan on taking those funds (profit from the flip) and either (a) investing it in other self directed eligible assets (RE, LLC interests, etc.) or (b) transferring it back to a traditional brokerage firm and to simply invest it in equities.  

How can you produce profits when your financing options have interest rates that are much higher than those offered by banks?

Honestly that looks like $20k +/- profit.
